Membrane PP Filter Fabric - 
COX Filter Cloth use the high quality PP fiber to manufacture kinds weight(350, 400, 450, 500, 550, 600, 650, 700g) needle punched PP filter felt fabric. PP material filter media have some properties than polyester felt fabric, such as ordinary filter fabric have the properties of anti-acid, anti-alkali and lower soften point, and its stability of water solution is excellent, so PP needle punched filter felt is often used in the field is fume temperature under 100℃, the density of acid and alkali is high or the field of filtering solid from liquid that the density of acid and alkali is high. Polypropylene filter fabrics are applied with press-in style, suction style, bags style, centrifuge style etc liquid filtration equipment. The PP needle punched felt can used in liquidsolid filtration, selects different specifications of PP fibers and ordinary staple scrim or high strength filament scrim. That grams different from 350g/m2~700g/m2 and thickness different from 1.2mm~4.5mm all can be produced in our company, and can be divided into different widths. The post finished treatment includes singeing, calendaring etc.
